High-High-Precision CNC Grinding Parts for Critical Flow Control Applications
At Xierge Precision Machinery Co., Ltd., we leverage over 30 years of manufacturing heritage since 1990 to engineer premium High-Precision CNC Grinding Parts for the medical, automotive, and industrial machinery sectors. Fluid connectors—such as luer fittings, quick-disconnect couplings, and threaded hydraulic adapters—demand absolute leak-proof integrity, complex internal geometries, and flawless surface finishes to prevent pressure drops and contamination.
Our production facility is equipped with Japanese imported Star CNC Swiss-type lathes and advanced multi-axis machining centers. This specialized equipment allows us to machine intricate internal threads, precise O-ring grooves, and micro-cross holes in a single setup, ensuring extreme concentricity and eliminating secondary clamping errors. The Swiss-type guide bushing technology provides unparalleled support, allowing us to produce long, slender fluid connectors with tight tolerances and superior cylindricality.
Adhering to our principle of "Integrity Oriented, Quality Foremost," we exclusively adopt premium raw materials, including medical-grade 316L stainless steel, naval brass, and high-strength aluminum alloys. To guarantee reliable product performance in pressurized environments, we apply strict quality inspection protocols utilizing a complete set of testing instruments imported directly from Japan and Germany. We continuously keep innovating to maintain sound business development, and we warmly welcome domestic and overseas clients to visit our factory and explore custom OEM/ODM cooperation opportunities.

- Complex Single-Setup Machining: Multi-axis live tooling allows us to turn, thread, and drill micro-cross holes simultaneously, maintaining absolute concentricity without secondary clamping errors.
- Medical & Automotive Grade Materials: We strictly source certified 316L stainless steel and naval brass, ensuring our fluid connectors withstand corrosive fluids, temperature fluctuations, and high mechanical stress.
- Ultra-Clean Internal Passages: To prevent flow contamination, all connectors are processed through our industrial ultrasonic cleaning machines to remove 100% of micro-burrs and cutting fluids from internal bores.
- Corrosion-Resistant Surface Engineering: We offer advanced treatments like electropolishing and passivation for stainless steel, reducing surface friction and preventing biofilm buildup in medical applications.
- World-Class Metrology Assurance: Utilizing Japanese and German imported thread gauges and CMMs, we conduct rigorous dimensional and geometric inspections on critical sealing threads and diameters.
- 30+ Years of OEM/ODM Innovation: Established in 1990, our engineering team collaborates closely with clients to optimize DFM (Design for Manufacturing), seamlessly transitioning custom fluid connector designs into mass production.
Payment Methods & Global Logistics Solutions
Secure International Payment Terms:
To facilitate smooth B2B international trade, we offer flexible and secure payment options. For mass production orders of High-Precision CNC Grinding Parts, we accept standard T/T (Telegraphic Transfer) with a 30% advance deposit and 70% balance before shipment. For large-scale international supply contracts, we are fully capable of processing Irrevocable Letters of Credit (L/C) at sight. For initial prototyping, sample orders, or custom tooling fees, PayPal and Western Union are also available to expedite the process.
Global Logistics & Protective Packaging:
We provide comprehensive end-to-end shipping solutions under FOB, CIF, and DAP Incoterms. For urgent prototypes or small batches, we utilize expedited international couriers such as DHL, FedEx, and UPS. For bulk mass production, we offer highly competitive sea freight (LCL/FCL) and air cargo rates through our trusted global forwarder network. Recognizing that fluid connectors have delicate sealing surfaces and fine threads, we utilize specialized packaging: each connector's threads and O-ring grooves are protected with plastic caps, wrapped in VCI (Volatile Corrosion Inhibitor) anti-rust paper, and secured in custom EPE foam slots within sturdy export-grade cartons or wooden cases to prevent any transit damage.
FAQ
Leak prevention is paramount for fluid connectors. We machine O-ring grooves using our Japanese Star CNC Swiss-type lathes, which provide extreme tool stability. We tightly control the groove width, depth, and diameter to tolerances within ±0.01mm. Furthermore, we use imported Japanese optical comparators and micro-meters to inspect every groove, ensuring the optimal squeeze ratio is achieved for a flawless seal.
Yes. We have mature processing parameters for 316L stainless steel. For medical applications, we machine the internal fluid paths to a smooth surface finish (Ra 0.4) and then coordinate electropolishing and passivation treatments. This not only improves corrosion resistance but also removes microscopic burrs and reduces surface friction, preventing biofilm buildup.
Internal debris can severely damage pumps and clog critical fluid lines. After machining and deburring, all fluid connectors go through our dedicated industrial ultrasonic cleaning machines. This process, combined with high-pressure flushing, ensures that all micro-burrs and cutting fluids are completely removed from blind holes, threads, and internal cross-holes before packaging.
With over 30 years of expertise, we are fully equipped to machine all major international thread standards, including NPT, BSPP (G), BSPT (R), Metric (M), UNF, and specialized medical Luer threads. We use imported Japanese and German thread gauges to perform 100% inspection on critical sealing threads to ensure perfect mating.
Absolutely. We continuously keep innovating and support clients from the R&D phase. We provide agile prototyping services with lead times as short as 7-10 days for first articles. Our engineering team will review your CAD models to provide DFM (Design for Manufacturability) feedback, helping you optimize flow dynamics and reduce machining costs before scaling to mass production.
Machining softer materials requires precise tool geometry and cutting parameters to prevent galling and material adhesion. Our Star CNC Swiss-type lathes utilize specialized polished cutting tools and optimized feed rates to achieve excellent surface finishes on brass and aluminum, preventing deformation of barbs and threads in low-pressure fluid applications.
